Application filed February 20, 1917. Serial No. 149,828.

To all whom it may concern:

Be it known that I, ANDREW B. GRoDAns, a subject of the King of Great Britain, residing at Antelope, in the Province of Saskatchewan, Dominion of Canada, have invented certain new and useful Improvements in lVell-Curbings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to well curbings.

The object of this invention is to construct an improved form of well curbing which will give proper access to the water, while properly retaining the surrounding soil, but particularly Where it is of a shifting nature such as quicksand. In connection with this curbing it is an object to so inclose the reservoir formed by the curbing as to prevent gophers and mice from falling into the well. To this end, the construction contemplates a curbing formed of sections or slabs fitted together to form a complete inclosure, and to fiX sections with seepage openings across which meshed material is stretched in order to retain quicksand or other shifting soil or sand which might form part of the geological formation.

lVith the above objects in View and such other objects as may hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings:

Figure 1 is a vertical section through a well constructed according to my invention,

Fig. 2 is a horizontal section on line 22 of Fig. 1,

Fig. 3 is a modified form of the invention, and

Fig. 1 is a section on line 41-1 of Fig. 3.

Referring more particularly to the drawings, in Figs. 1 and 2, 1 represents opposite walls of a rectangular curbing, and 2 the connecting walls between the walls 1. The walls 1 and 2 may be formed of any suitable material, such as metal sheets or concrete slabs, and the walls 1 are provided with the laterally projected flanges 3 which inclose the walls 2, the latter also having interlocking flanges 3. Formed on the bottoms of the walls 1 and 2 at suitable points, are the openings 41 across which is stretched the meshed fabric 5. In the case of concrete slabs, the fabric is molded into the slabs when the latter are manufactured. The bottom of the tubing is closed by means of a plate 6 having the upstanding flange 7 which is spaced from the edges of the plate and forms with the walls 1 and 2 trough or channel for a cement sealing strip 6. At its upper end, the curbing is provided with a cap plate 8 which has the marginal downturned flange 9 which seats over the upper edges of the walls 1 and The cap plate is preferably pyramidal in form, and at its apex is provided with an opening 10 through which the pump tube may be lowered. The

sides 1 and 2 are united by means of cleats l2, and the bottom is held in position by means of cleats 13. In assembling the device, the bottom. 6 is lowered through the shaft formed by the walls 1 and 2, and then fastened and sealed, it being noted that the bottom is of smaller dimension than the well casing.

In the forms shown in Figs. 3 and 1 the curbing provides a cylindrical reservoir, and is preferably made of two semi-cylindrical sections 12 and 13 having the marginal flanges 11 which permit the sections to be interlocked to provide a sand-proof casing. The walls of the sections are interrupted by openings 15 which have the meshed material 16 stretched thereacross as hereinbefore described, and provides for the entrance of water to the reservoir. The bottom of the reservoir or curbing is a circular plate 17 seated inside the curbing 14.- and held in place by means of cleats 17. .A conical flanged cap 19 closes the upper end of the casing. The peak of the conical cap is provided with an opening through which the pump tube may be removably inserted so that no ditliculty will be experienced in removing the pump for repairs. A spaced flange 18 provides with the curbing a cement channel which may be filled to prevent the access of sand to the casing.

In practice, the curbing is used to wall up the well opening in any suitable dimension both as to diameter and height after which the cap is fitted over the reservoir completely inclosing the latter. The pump is then inserted in position and the remaining depth of the well opening, if desired, may be filled with earth. In this manner, a completely inclosed well is provided, and gophers and mice are wholly prevented from falling into the well. The pump tube may extend substantially to the bottom of the Well so that a water supply is always to be had, the latter finding its Way into the reservoir through the openings 4 and 15, in a clean condition, the fabric stretched across the openings preventing sand or other soil from falling into the Well opening. Because of this, the well will not fill up with sand and the pump bottom does not become so clogged as to cause sand to be pumped with the Water.

lVhat I claim as my invention is A well curbing comprising a plurality of interfitted plates forming the walls of the curbing, said walls having seepage openings therethrough, meshed fabric stretched across the openings, a bottom plate and a cap plate, said cap plate having an opening for a pump, and a flange on said bottom plate spaced from the walls to provide a sealing channel.

In testimony whereof, I afiix my signature, in the presence of two Witnesses.
